Live online course – starts on 6 October 2020. Course full - add your name to the waiting list.

Layer of protection analysis (LOPA) is a semi-quantitative tool for analysing and assessing risk on a process plant. It uses an order of magnitude technique to evaluate the adequacy of existing or proposed layers of protection against known hazards.

This online course will help you understand how significant scenarios are categorised and tolerable frequencies assigned for identified hazardous events. You will also learn to assign risk categories and determine how many Independent Protection Layers (IPLs) should be in place. The course also covers the specification and requirements for a protection layer to be accepted as an IPL.

All the essential LOPA steps are practised in virtual workshops, including the use of software tools. Course materials also include a compendium of LOPA research papers, reference materials and further reading.

Teaching will be delivered via two live modules (approximately three hours in length each), alongside independent study and pre-recorded video sessions issued before/between modules.

An e-certificate will be issued at the end of the course to confirm attendance and CPD hours logged.

Learning outcomes

By the end of this course you will understand:

  • the LOPA methodology and its application
  • how to decide if a process needs a safety instrumented system (SIS)
  • what safety integrity level (SIL) is required
  • how to define an Independent Protection Layer (IPL)
  • how to implement a process to manage these systems through the life cycle of an installation
  • how to lead a LOPA study.

Who will benefit

  • Process safety engineers
